Application filed November 14, 1904. $eria1No. 232,688.

T 0 (tiltwhmn it nwly concern.-

Be it known that I, GEORGE W. LENTZ,aeitizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Dies, of which thefollowing is a specification.

In the production of embossed woodwork it has heretofore been foundimpractical to closely imitate carved effects because of theimpossibility from a practical standpoint of producing deep depressionsin the surface. This failure has been due to the fact that when anembossing-die was provided with extremely high cutting-points thesepoints when sinking into the wood would cause the wood to splitlongitudinally.

The object of my present invention-is to produce means, either formedintegrally with or operating automatically in conjunction with a cuttingand embossing die, by which the material operated upon will beautomatically transversely compressed and prevented fromsplittinglongitudinally during the time of operation.

The. accompanying drawings illustrate my invention.

Figure 1 is a perspective view of a die constructed in accordance withmy invention. Fig. 2 is a transverse section of the die, a piece ofmaterial to be embossed, and the upper and lower beds of anembossing-maehine.

The main body 10 of the die is provided on its work-face with anydesired embossing-pattern 11 having high cutting portions, and I findthat the difference in level between the highest and the lowest point ofthe die may be as much as one-half inch and under some circumstanceseven more. Flanking the pattern-surface 11 along the entire length ofeach side is an abutment 12, the insides 13 of which are preferablytapered slightly inward. The abutment 12 may be interrupted at placeswithout departing from my invention. In

practice I find it most convenient to make the abutments 12 integralwith the body 10; but this is not necessary, as they may as well be madeseparate from the die and attached to the edges thereof or be attachedto the embossing-bed 14 immediately adjacent the sides of the die.

In operation the die 10 together with the abutments 12 are arranged inconjunction with asupporting-table 1 1, preferably of such kind as topermit the heating of the die in the usual well-known manner. Thematerial 15 to be embossed is of a width slightly greater than thedistance between the abutments 12 at a point just beyond the highestcuttingpoints of the surface 11, so that when the material is forcedinto engagement with the pattern-surface of the die the said materialwill be clamped between the abutments 12, and thus held againstsplitting.

I have found by actual practice that by the use of an ordinary diehaving very high cutting-points the proportion of loss is sometimes asgreat as forty per cent. of the total number of pieces embossed, whileby the use of my die repeated trials have failed to cause the splittingof a single piece.

I claim as my invention- 1. A die carrying on its face anornamenting-surface, said ornamentingsurfaoe being flanked at oppositesides with abutments which project beyond the highest point of theornamenting-surface and their adjacent faces convergent toward the lowerportions of the ornamenting-surface.

2. A die carrying on its face an ornamenting-surface, saidornamenting-surface being flanked at opposite sides with abutments whichproject beyond the highest point of the ornamenting-surface and theadjacent faces of which taper inwardly.

3. A die carrying on its face an ornamenting-surface having high cuttingportions, said ornamenting-surface being flanked at opposite sides withabutments the adjacent faces of In witness whereof I have hereunto setmy which project beyond the highest cutting hand and seal, atIndianapolis, Indiana, this points and which taper inwardly, whereby ma-9th day of November, A.
